2D, 3D and n-dimensional vector magnitude.
var magnitude = require('magnitude') magnitude([ 0, 1, 0 ]) //=> 1 magnitude([ 0, 4, -3 ]) //=> 5
Or the squared magnitude (to avoid a
var magSqr = require('magnitude/squared') magSqr([ 0, 4, -3 ]) //=> 25
npm install magnitude --save
len = require('magnitude')(vector)
Returns the vector magnitude of the given n-dimensional vector array.
lenSqr = require('magnitude/squared')(vector)
